'FINISH-REMOVER.

No Drawing.

To all whom it may concern Be it known that I, CARLETON ELLIS, a citizenpf the United States, and resident of Montclair, county of Essex, andState of New Jersey, have made a certain new and useful InventionRelating to Finish-Removers, of which the following is a specification.

This invention relates especially to finish removers comprising phenolcamphor or similar compounds, together with incorporated volatileorganic solvent material and waxy or other suitable stifi'ening materialif desired. Various solid camphor terpenes have the peculiar property ofcombining with phenols in definite proportions so as to form compoundswhich have distinctive properties Widely different. from the com-.

ponents used. Ordinary laurel camphor, Borneol camphor and theturpentine camphors or their derivatives may be combined in this waywith carbolic or cresylic acids. For instance, pure crystallizedcarbolic acid vwhich melts at 43C. when combined with laurel camphorwhich melts at 175 C. forms a liquid solvent. melting much below zero.

Such combinations may be effected when the I -stance, these camphoratesolvents may be first formed and then incorporated with other removeringredients or may be conveniently formed by bringing the componentstogether in solution with the other remover ingredients. These camphoricterpenes seem to combine most readily in equimolecular proportions,although not only a camphorate but a bicamphorate can be formed withcarbolic acid or with other phenols, such, for instance, as cresylicacid. These compounds are heavy liquids having .a very general anddesirable solvent action on many paint or varnish gums, resins orbinders so as to be desirable components for finish removers. It is alsodesirable to incorporate a suitable small proportion of such practicallynon-volatile material in removers to prevent any possibility of thedrying out of finish on which waxy removershave actedto soften or,loosenthe same.

Specification of Letters Patent. Patented Nov 24, 1914, Applicationfiled April 1, 1912. Serial No. 687,770.

In this way even under extreme service conditions it is practicallyimpossible for the wax or treated finish to form an undesirably hardcoating even if allowed to stand for unusually long periods.

The main remover solvents may comprise loosening. finish solventmaterial, that is solvents of a generally alcoholic character or actionin removers, such as methyl, ethyl,

propyl, butyl, benzyl and other strict alcopenetrating finish solventmaterial may also e be used, that is solvent material of a gen erallybenzolic character or action 1n remqw'g.- ers, such as benzol and itshomologues,

toluol, xylol and their commercial forms, such as commercial toluol,solvent naphtha;

and the somewhat analogouspetrolemnnydrocarbons, such as naphtha andbenzin and the chlorinated derivatives, such as' chlorbenzol,chlortoluol and other chlorinated solvents, such as carbon-tetrachlorid,tetrachlorethane and the like, and also turpentine, wood turpentine andvarious esters an .pentine, pine oil and so forth,;by nascent hydrogenas by agitation of the solvent with sodium, potassium or the like or byother treatment with hydrogen in the presence of active metallicmaterial, such as platinum,

d ethers, such as: bet'anaphthol ether, benzyl.

palladium and so forth. Suitable heavy solvents, such as may be used tominimize any tendency to drying out of the remover may compriseepichlorhydrin, dichlorhydrin or chlorinated lycerole or ethyl or methylphenates. thyl phenate and methyl phenate and the correspondingcresylates are also desirable solvents which may be convenientlyproduced in various ways, the combination of the components beingfacilitated by suitable catalytic material such as aluminum oxid,thorium oxid or the like at a temperature of 350 to 400" C. or so, thethorium oxid having especially desirable catalytic action in thisconnection and promoting the formation of these particular compoundswhen the components are brought together in this way.

Su1table stilfening material may be used in such removers preferablycomprising suitable Waxy evaporation-retarding material, such-asparafiin, ceresin or other mineral wax, although beeswax and other waxybodies may be used and also other stifiening material, such as celluloseesters, nitrocellulose, which may be used in the form of scrap celluloidwhich usually contains nitrocellulose and suflicient incorporatedcamphor to combine with phenol and form the camphorated solventsreferred to. llnert stidening material may also be incorporated ifdesired, such for example as wood flour, starch, infusorial earth,whiting and the like, it being of course understood that the solublethickeners are preferably methyl acetate, 20 parts of benzol, 10 partsof benzyl alcoholp l parts of laurel camphor, 10 parts of scrawould-contain nitrocell ose, and about 4 parts of camphor,'6 artsofcarbolic acid and 2 parts of parafin.
